Sustainable Mobility: Milestones in Climate Protection and Innovation in 2024

Date: 2025-03-17

Lübeck-Travemünde – Over the past year, TT-Line has made significant progress in reducing CO₂ emissions and promoting sustainable mobility. Since 2010, fleet emissions on German routes have already been reduced by 35% per transport unit. This milestone highlights the company’s long-term commitment to environmentally friendly transport solutions.

In 2024, the impressive milestone of one million transported passengers was surpassed—passengers who chose a sustainable and efficient mode of travel across the Baltic Sea.

The fuel efficiency of the fleet was further improved as well. By integrating bio-LNG into the fuel mix, substantial CO₂ savings can be achieved compared to conventional fuels.

By offering the option to purchase bio-LNG and enable CO₂-free travel, customers are given a sustainable choice for environmentally friendly mobility. The commitment to responsible consumption and efficient use of resources remains one of the company’s top priorities.

In addition, TT-Line expanded its intermodal network: starting in 2024, the Trelleborg hub offers new connections to Narvik, Sundsvall, and Hallsberg. This initiative strengthens sustainable transport routes by shifting freight transport from road to rail and ferry, while also improving connectivity.

TT-Line employs various systems to increase fleet efficiency across all areas. These include fleet-wide AI-driven voyage optimization, which already led to a reduction of 3,500 tonnes of fuel consumption in 2024. The voyage optimization calculates savings potential based on the difference between the planned route and the AI-calculated optimal route and speed.

A particularly important contribution to sustainability is the reduction of food waste. Through efficient buffet planning and portion-controlled production, food waste was reduced by a total of 20% in 2024.

TT-Line’s progress in emission reduction, sustainable mobility, and energy efficiency also includes key achievements such as the official partnership with UNESCO World Engineering Day, the expansion of shore power supply as part of the Green Shipping Corridor Initiative, and the innovative graphite coating of the Nils Dacke.

TT-Line as an Official Partner of UNESCO World Engineering Day 2025

As a leading shipping company in the field of sustainable transport in the Baltic Sea, TT-Line has been selected as an official partner of the UNESCO World Engineering Day for Sustainable Development (WED) 2025. As part of this partnership, a film was produced showcasing TT-Line’s commitment and efforts in detail.

WED is jointly organized by UNESCO and the World Federation of Engineering Organizations (WFEO), which represents around 100 countries and more than 30 million engineers worldwide. This international day, proclaimed by UNESCO, aims to raise awareness of the importance of engineering innovations for sustainable development.

Jacques de Mereuil, Executive Director of WFEO, highlights the significance of WED:
“World Engineering Day 2025 is about putting engineering in the global spotlight, demonstrating how engineers are leading efforts to achieve the UN Sustainable Development Goals, and inspiring the next generation to learn more about what a career in engineering has to offer.”

The foundation of this partnership includes, among other things, TT-Line’s commitment within the Green Shipping Corridor Initiative, the associated installation of shore power connections on its ferries, and the continuous expansion of its intermodal network.

TT-Line’s efforts also focus on the use of innovations such as AI-based voyage optimization, waste heat recovery systems, and hydrodynamic ship design to increase efficiency and reduce emissions.

In particular, the LNG-powered Green Ships Nils Holgersson and Peter Pan, which have been awarded five stars in the Clean Shipping Index, combine a wide range of technological innovations. For example, when operating on LNG, these vessels significantly reduce emissions per transport unit compared to conventional marine diesel. This results in savings of up to 60% in CO₂ emissions, 93% in particulate matter emissions, and 98% in sulfur oxides. In addition, the Green Ships offer the option of using climate-negative bio-LNG, enabling CO₂-free travel for customers.

As an official partner, TT-Line’s insights and expertise are an integral part of the campaign, which provides governments, UN organizations, policymakers, educators, and leaders from the public and private sectors with a platform to shape a sustainable future through innovation and engineering.

Expansion of Shore Power Supply: TT-Line Strengthens Sustainable Shipping

Another important step toward sustainability is the expansion of shore power capacities as part of the Green Shipping Corridor Initiative. In cooperation with BordstromTech, the German Federal Ministry for Digital and Transport, and the ports of Travemünde and Trelleborg, TT-Line has equipped its four largest ferries—Nils Holgersson, Peter Pan, Tinker Bell, and Akka—with shore power systems. The onboard installation has already been completed, enabling the vessels to connect to the local power grid during port stays, thereby reducing emissions as well as air and noise pollution in port cities.

At the same time, preparations have now been successfully completed at the Świnoujście ferry terminal to connect the TT-Line ferry Peter Pan to the shore power supply system (OSP – Onshore Power). This represents a significant advancement for the region, as it allows for a substantial reduction in exhaust emissions and noise. With this, TT-Line continues its strategy of minimizing environmental impact and actively supports the implementation of the “Green Port” initiative at the Port of Świnoujście.
